Concept explainers
Two identical 40-lb curling stones have diameters of 11 in. and may slide on a sheet of ice. Stone B is at rest when stone A strikes it, moving it to the center of the inner circle. The distance A travels before striking B is 108 ft, and the sweepers scrubbing the ice reduce the coefficient of friction between A and the ice to 0.04, while the coefficient of kinetic friction between B and the ice is 0.1. The coefficient of restitution between A and B is 0.6. Neglecting rotation, and knowing that B travels 4 ft along the dotted line, determine (a) the distance b, (b) the speed A has when it is released 108 ft from the impact.
